What it does

Perform a comprehensive code health check on a directory. Use when the user asks to analyze code quality, find issues, or get a health report.

Code Health Check

Analyze the codebase at $ARGUMENTS and produce a structured health report.

Checks to Perform

1. File Organization

  • Are files reasonably sized? (Flag files > 200 lines)
  • Is the directory structure logical?
  • Any files that look misplaced?

2. Error Handling

  • Are async operations wrapped in try/catch?
  • Are errors propagated correctly (not swallowed)?
  • Is there a global error handler?

3. Security Basics

  • Any hardcoded secrets, API keys, or passwords?
  • Any use of eval() or similar dangerous functions?
  • Are user inputs validated before use?

4. Code Quality

  • Any obvious code duplication (similar blocks in multiple files)?
  • Any unused variables or imports?
  • Are function signatures reasonable (not too many parameters)?

5. Dependency Hygiene

  • Are all imported modules actually used?
  • Any circular dependencies?

Severity Levels

Use these to categorize issues:

SeverityMeaningExample
CRITICALMust fix immediatelyHardcoded secrets, SQL injection
WARNINGShould fix soonMissing error handling, large files
INFONice to improveMinor duplication, naming conventions

Output Format

Return a structured report in this exact format:

# Code Health Report: {directory}

## Overall Score: {A/B/C/D/F}

## Summary
- Files analyzed: {count}
- Issues found: {critical} critical, {warning} warnings, {info} info

## Critical Issues
{list each with file:line and description}

## Warnings
{list each with file:line and description}

## Info
{list each with file:line and description}

## Recommendations
{top 3 actionable recommendations}
